tion, reference being had to the accompanying drawings.

This invention relates to means for elevating grain and the like, and isespecially adapted for elevating grain from the platformcanvas orcarrier-apron of a harvester to the binder deck or table.

My invention has for its object to provide a simple and effieientmechanism that will eifect positive elevation of any and all kinds ofgrain, that will accommodate itself to these varying kinds andconditions of the grain, that will perform its functions with greaterease and accuracy, and that will secure the grain from waste by fallingoff or being blown oii' the elevator.

In self-binding harvesters the elevation of the grain to thebinder-table has been heretofore effected by means of an elevating apronor canvas having cross-bars, that travels upwardly and carries the grainover and on top, where it is exposed to the action of the winds, &(3-This elevating means is disadvantageous in many other particulars, amongwhich maybe mentioned the fact that it does not.

hold the grain compactly while it is being elevated, so that it isdelivered on the bindertable in a diffused and scattered gavel; butin myinvention the grain is elevated by thelower or under strand of anendless apron, and is held against guides under the elevating mechanismby elastic teeth, which also carry it upwardly between the said guidesand elevator.

By this'means the grain is held on all sides the ribs D as it is beingelevated.

Referring to the drawings, A designates the frame of the elevator,whichis in this instance arranged like the ordinary apron-elevator frame, andconsists of side boards, B B, and the inclined bottom 0. On the bottom Gare secured a number of parallel guiding and supporting ribs or strips,D, on which the. grain rests as it is being elevated, and each sideboard, B, carries chain-pulleys E E at its top and bottom. On both ofthese pairs of pulleys E E travel chain belts F F, the links of whichare provided at suitable intervals with lateral lugs or extensions G G,having 6 perforations H. These lugs G G enter the kerfs I I of thebifurcated ends of the crossbars J, and the latter are by this meanssecured on the chain belts F F, a bolt, K, being passed through eachbifurcated end I and lug G.

L designates the spring carrier-teeth that are secured on the cross-barsJ. These teeth L are arranged in pairs M, that are formed of a singlepiece of elastic wire, N, comprising a straight central portion, 0,which is secured to the cross-bar J by staples 1, and has each endcoiled round the cross-bar, as at Q, and extended out to form the toothL. The coils Q, admit of additional elastic movement on the part of theteeth, which have their points It bent slightly, as shown. The teeth Ltravel between the ribs D as the cross-bars are carried by the chainbelts F F at the sides of the elevator.

S designates a number of endless bands that aredisposed longitudinallyand are arranged around the cross-bars J, the function of saidbandsbeing to retain the grain down against The operation and advantagesof my invention are obvious. The two chain belts are driven in thedirection shown by the arrows by suitable mechanism connecting them withthedrive-wheel. Thegrainiscarried upwardly 5 by the spring-teeth, whichpass between the ribs D and the under side of the elevator mechanism,which latterot course moves upwardly,

combination of the frame A, having inclined 1 they are supported but notconnected to the 10 bottom 0, the parallel guiding and supporting stripsD, secured longitudinally on the said bottom, the elevating mechanismhaving the 5 cross-bars J, carrying spring-teeth L, having the bentpoints R, that engage the bottom 0 and travel one between each twoofsaid strips D, and the endless bands or cords S, disposed longitudinallyaround the bars J, by which said bars, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
